# actest.m4 -*- autoconf -*-
# Additional Autoconf macros to ease testing.
# AC_STATE_SAVE(FILE)
# ------------------
# Save the environment, but the variables we are allowed to touch.
# This is to check no test touches the user name space.
# FIXME: There are surely better ways. Explore for instance if
# we can ask help from AC_SUBST. We have the right to touch what
# is AC_SUBST.
# - ^ac_
# Autoconf's shell name space.
# - ALLOCA|NEED_SETGID|KMEM_GROUP
# AC_FUNCs from acspecific.
# - AWK|LEX|LEXLIB|LEX_OUTPUT_ROOT|LN_S|M4|RANLIB|SET_MAKE|YACC
# AC_PROGs from acspecific
# - _|@|.[*#?].|LINENO|OLDPWD|PIPESTATUS|RANDOM|SECONDS
# Some variables some shells use and change.
# `.[*#?].' catches `$#' etc. which are displayed like this:
# | '!'=18186
# | '#'=0
# | '$'=6908
# - POW_LIB
# From acfunctions.m4.
#
# Some `egrep' choke on such a big regex (e.g., SunOS 4.1.3). In this
# case just don't pay attention to the env. It would be great
# to keep the error message but we can't: that would break AT_CHECK.
